Stock value calculation error in Tally

Hi friends, i found an error in average  cost  stock value calculation in Tally software. In Tally allow negative stock option. Apply  negative stock entry to a particular product, after that purchase some quantity and make the stock to zero. Then purchase some more products,then the stock value is taken by multiplying quantity to average rate, instead of taking weighted average rate.

         I think it is an mistake, otherwise please give the details to me by sending mail to  admin@faceoftruth.com.
